Flat Solar Collector

Copper aluminum compound anodizing board core collector uses the copper aluminum compound craft, after the rolling forms the bronze flow channel and the aluminum nature heat absorption wing piece, the board core surface forms the selective heat absorption coating after the anodizing, the surface layer adhesion is good, anti-corrosive, the life is long, the thermal efficiency is high.
entire red copper selectivity spreads plywood core collector to use the copper ultrasonic welding technology production, the bronze wing piece realizes the non-medium welding with the bronze drive pipe is a body or uses the high frequency autogenously welding technology production, the bronze wing piece with the bronze drive pipe non-medium fusion is a body, the header and the branch welds (melt) to meet directly, cannot the transition joint. Its surface uses the high quality selective coating or galvanizes the black chromium coating, the absorption rate is high, the emissivity is low, the adhesion is good, anti-corrosive, the life is long.
entire red copper nitrogen titanium oxide spreads plywood core collector to use the ultrasonic wave or high frequency welds the entire copper banding from the melt, the header and the branch welds directly, cannot the transition joint. Its surface uses the German nitrogen titanium oxide coating, the absorption rate is higher, the emissivity is lower, the adhesion is good, anti-corrosive, the thermal efficiency is high
